Be it known that 1, ROBERT WILLIAM lIc- GOWAN, a subject of the King of Great Britain, residing at Queenstown, in the State of Tasmania, Australia, have invented certain new and useful Improvements in Devices for Unstoppering Aerated-\Vater Bottles, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide an opener for bottles in which aerated water is confined, such bottles being of the class where the sealing of the bottle is obtained by means of gaseous pressure acting to hold a ball against an elastic ring inserted within the neck of the bottle. The method at present in use for opening such bottles is to push the ball by main force bodily away from its elastic seating, which method at the moment of such manipulation augments the pressure within the bottle, increasing the risk of fracture, and should such fracture take place greatly adds to the risk of injury to the hands of the operator.

By my improved opener a vent is formed to the interior of the bottle, so that the pressure within the same is gradually relieved, and the ball falls by gravity or can be pushed gently from its seating.

Reference being had to the drawings, in which like letters of reference indicate like parts, Figure 1 is a sectional elevational View of my device as applied to a bottle, the latter being shown in dotted lines. Fig. 2 is a sectional elevational View of the pusher. Fig. 3 shows the tongue, hereinafter described, in front and side elevation. Fig. 4: shows the tongue-retaining plug in side and end elevation, and Fig. 5 shows a modified form of the device as applied to a bottle.

A indicates a pusher formed with a circular depending flange B, adapted to take over the neck of a bottle and centrally provided with a circular recess 0. A plug D is adapted to fit within the recess 0 and be held therein by means of a screw D. The plug D is grooved,

as at D to allow for the reception of the upper part of a tongue E, the flanged-over end E of which is held between the plug D and the body of the pusher A.

Serial No. 69,868. (No model.)

The tongue E is so formed that the point thereof will when the pusher is applied to a bottle engage with the upper convex portion of the ball thereof and on pressure being applied to the pusher will be forced between the said ball and its corresponding elastic ring or seating and by compressing the latter at its point of contact will leave a small apertu re on either side of the said tongue, whereby the conflned gas may escape.

It is obvious that when the gaseous pressure is entirely removed the ball will drop on the withdrawal of the pusher; but, if desired, I may make use of the modified form of my invention shown in Fig. 5, wherein the plug D is elongated, so that after the pressure has been partly relieved through the action of the tongue E the ball can be gently forced downward by means of the said elongated portion of the plug D.

Having thus described my invention and in what manner the same is to be performed, I declare that what I claim is 1. An opener for aerated-water bottles comprising a circular pusher having an enlarged head portion, a body portion, a downwardlyextending circumferential flange below and integral with the body portion, a recess situated centrally within the lower surface of the said body portion, a plug adapted to fit within the said recess, a screw passing through the said body portion into the said plug, and a curved tongue projecting downwardly to a point within the plane of the lower edge of the said circumferential flange and fitting within a groove in the top and side of the said plug and held in position by the said plug, all substantially as described.

2. An opener foraerated-waterbottles,comprising a circular pusher having an enlarged head portion, a body portion, a downwardlyextending circumferential flange below and integral with the body portion, a recess situe atedcentrally within the lower surface of the said body portion, a plug adapted to fit within the said recess and projecting downwardly within the body portion and the plane of the lower edge of the circumferential flange, and a screw passing through the said body portion into the said plug, and a curved tongue projecting downwardly to a point within the plane of the lower edge of the said circumferential flange and fitting within a groove in the top and side of the said plug andheld in position by the said plug, all substantially as described.

3. A bottle-opener for inwardly-opening bottles sealed by a ball pressed upwardly by the pressure of the gas from within, comprising a cap adapted to inclose the upper end of the neck, and a pointed pusher projecting downwardly eccentrically from the interior of said cap and adapted to be inserted between the sealing-ball and its seat to pry open the seal, substantially as described.

4. A bottle-opener for inwardly-opening bottles sealed by a ball pressed upwardly by the pressure of the gas from within, comprising a cap adapted to inclose the upper end of the neck, a plunger depending within said cap, and a pointed pusher depending below said plunger.

5. A bottle-opener for inwardly-opening bottles sealed by a ball pressed upwardly by the pressure of the gas from within, comprising a cap adapted to inclose the upper end of the neck, an internal recess within the head of said cap, a plug fitting in said recess, and an eccentric downwardly-projecting pointed pusher secured and held between said plug and the wall of the recess, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
